Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How to fake mobility control in BP?

I ran into two situations where I needed control over component mobility in a graph but I was only able to solve one.
The first was when I had to change a mesh from being static to movable in the construction script based on some logic. I ended up with two static mesh components, one static, one movable, with only one of them visible and colliding at any given time. Hacky but good enough.

However the same trick doesn't work when it comes to light components and fixing the "more than four stationary lights are overlapping" warning. Since the AffectsWorld flag can't be set in BP I figured I set intensity to zero on the ignored light component. However that does not seem to affect the automatic light channel assignment, so the now totally dark lights are using up channels meant for actually visible ones. Makes sense as in theory I could turn them back on anytime, but it made me wonder if there is a more proper workaround for mobility control.
